现在大街上最靓丽的是啥?一排排小橙，小绿，等等五颜六色的自行车喽～

　　现在共享单车这么火，关于它们的表达同学们都清楚吗?

　　共享单车(shared bikes)是现在在城市中非常流行的短途(short distance)出行工具, 因为它们的方便，健康环保，越来越多的人选择共享单车出行。我们也来跟风趁热学学一些表达来积累些语料吧，要知道在我们托福考题中可使出现过不少类似交通工具的内容哦～

　　首先我们来看看怎么描述共享单车，它们是怎么样的一种存在呢?我们来看一篇关于它的新闻节选。

　　“ China’s craze for bike-sharing has brought more than 2m new bikes to its city streets. The brightly coloured bicycles, produced by companies such as Mobike and ofo, can be unlocked using mobile apps. Mobike’s models are even GPS-tracked.

　　中国的共享单车热潮已为其城市的街头巷尾增添了逾200万辆新自行车。摩拜单车(Mobike)和ofo等公司推出的这些色彩鲜艳的自行车可用手机应用解锁。摩拜的自行车甚至可用GPS追踪。

　　Unlike other sharing schemes around the world, China’s bicycles can be picked up and left anywhere, making them convenient for users but frustrating for city authorities

　　与全球其他共享项目不同，中国的共享单车可在任何地方取用和停放，虽然方便了用户，但让城市管理部门感到头疼。

　　The bicycles are locked by the user after riding, and then unlocked by the next rider by using a mobile app and scanning a QR code on the frame.

　　用户骑完共享单车后将之上锁，下一个用户可使用手机应用扫描车身上的二维码解锁 ”

　　好了，看完上面这段话，请同学们试着找出关键词，总结一下到底怎么介绍共享单车呢(shared bikes)?

　　我们可以这样说，The shared bike is the most popular mode of transport for short distance recently especially among young citizens. They can be picked up and left anywhere, which is a great convenience for users. After you find one, you only need to scan a QR code on the frame to unlock it. After you get to the place, you can lock up the bike manually. It’s charged 0.5-1 RMB per hour. The 2 best-known and most widely used bikes are called Mobike and Ofo. You need to download their App , pay certain amount of deposit and then you are free to set off on the road. The bikes even have GPRS-Trackers on them so that you get to know where to find one available on your phone. Occasionally, some promotions are offered for users like free ride or red-packet bikes , which makes this cycling activity even hotter.

　　(共享单车是现在国内最流行的短途出行工具尤其是在城市年轻人中。它们可以被放置在任何地点，这很大限度地方便了用户。你找到一辆单车后，只需要扫一下车上的二维码就可以解锁它。到达目的地后你手动关锁行程就结束了。共享单车每小时收费0.5-1块钱不等。现在最有名和最广泛的两种单车是摩拜单车和小黄车。你需要下载他们的app，交一定数量的押金就可以上路了。这些车上甚至有GPRS 定位装置，你可以通过手机知道哪里有车。单车时不时会有些优惠活动，像免费骑行或红包车，这让骑行越来越火了。)

　　那这就是我们一篇托福的语料了。

　　那我们现在再来按照托福考试独立任务题的2题模式Brainstorm一下shared bike 的advantages 和 disadvantages 分别是什么?

　　首先来说 Advantages：

　　1 convenient (从刚才的语料中可以提取);

　　2 a good exercise for body —cycling;

　　3 moneysaving

　　4 Never have to be afraid of bike missing.

　　5….(等你来填充)

　　Disadvantages:

　　1 hard to maintain，

　　2 dangerous riding

　　3 bad weather ( rain, snow, wind, sunburn)

　　4 time consuming for especially long distance.

　　5 ……(自己试一试)

　　同学们试着根据这些提示来分别表达一下shared bike的优缺点吧。

　　近期，国家出台意见稿鼓励共享单车实名制。

　　“ Recently, the ministry of transport released a draft guideline to encourage and regulate the development of shared bikes, soliciting public opinions for two weeks. The draft requires real name registration for shared bikes.

　　意见稿还指出，要加强信用管理，建立企业和用户信用基础数据库(establish an enterprise and user credit database), 将企业和用户不文明行为和违法违规行为记入信用记录(uncivilized behaviors and violations by enterprises and users will be written into their credit record), 建立守信激励和失信惩戒机制。
